好吧，我已经设法自己弄清楚了.我必须在其自己的dto映射中指定嵌套属性选项.但是，请告诉我是否还有另一种更好的方法

Well I have managed to figure it out by myself. I have to specify the nested property options in its own dto mapping. However let me know if there is another better way of doing this

  Mapper.CreateMap<EntityType, EntityTypeDto>()
                .ForMember(dest => dest.Properties, opt => opt.Ignore());               
            Mapper.CreateMap<Node, NodeDto>()
                .ForMember(dest => dest.ChildNodes, opt => opt.Ignore());
